General
Description
The TYCO DV-5aAutomatic Water
Control Valve Deluge Dry Pilot Actu-
ation are diaphragm type valves that
can be used in deluge fire protection
systems. When properly trimmed, the
double seat design of the DV-5aValve
also provides actuation of fire alarms
upon system operation.
The diaphragm style design of the
DV-5aValve allows external resetting,
providing for easy resetting of a deluge
system without having to open a valve
handhole cover to manually reposition
a clapper and/or latch mechanism.
Simply re-pressurizing the diaphragm
chamber resets the valve.
The DV-5afeatures internal and exter-
nal coating of the valve to provide
corrosion resistance. The external cor-
rosion resistance of the epoxy coating
permits the use of the DV-5ain cor-
rosive atmospheres associated with
many types of industrial processing
plants and outdoor installations.
The DV-5aDeluge Dry Pilot Actuation
Valve is offered with the DV-5aValve
and separately ordered semi-assem-
bled trim, as shown in Figure 5.
The DV-5aDeluge Dry Pilot Actua-
tion Valve is offered with or without a
System Main Control Valve.
NOTICE
The DV-5aValves described herein
must be installed and maintained in
compliance with this document, as
well as with the applicable standards
of the NATIONAL FIRE PROTECTION
ASSOCIATION (NFPA), in addition to
the standards of any other authorities
having jurisdiction. Failure to do so
may impair the performance of these
devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.

Operation
The TYCO DV-5aValve is a diaphragm
style valve that depends upon water
pressure in the Diaphragm Chamber
(See Figure 2A) to hold the Diaphragm
closed against the water supply
pressure.
When the DV-5aValve is set for service,
the Diaphragm Chamber is pressurized
through the trim connections from the
inlet side of the system’s main control
valve.
Opening the Dry Pilot Actuation trips
the Model MRA-1 Manual Reset Actua-
tor. Tripping the MRA-1 releases water
from the DV-5aDiaphragm Chamber
faster than it can be replenished
through a 1/8 in. (3,2 mm) restriction
located in the diaphragm chamber
supply connection. Release of water
through the MRA-1 results in a rapid
pressure loss in the DV-5aDiaphragm
Chamber.The force differential applied
through the Diaphragm to hold the
Diaphragm in the set position is then
reduced below the valve trip point. The
water supply pressure then forces the
Diaphragm open permitting water to
flow into the system piping, as well as
through the Alarm Port to actuate the
system alarms (See Figure 2B).

Upon opening of the DV-5aValve, the
Model MRA-1 Manual Reset Actuator,
which is described in Technical Data
Sheet TFP1387, opens to constantly
vent the DV-5aDiaphragm Chamber
to hydraulically latch the DV-5ain the
tripped position until manually reset.
See the Dry Pilot Actuation section for
additional information.
Dry Pilot
Actuation
The Dry Pilot Actuation Trim forms a
part of the laboratory approval of the
DV-5aValves and is necessary for their
proper operation.
With reference to Figure 4, the Dry Pilot
Actuation Trim provides for installation
of a detection system consisting of pilot
sprinklers (heat detectors) and manual
control stations interconnected with
a minimum length of 56 ft (17,1 m) of
1/2 in. (DN15) steel pipe equivalent to
207 in.3(3400 cm3). The dry pilot line,
which is to be pressurized with air or
nitrogen, is connected to the Dry Pilot
Line Connection.
Dimensions are provided in Figure 7.
Pilot sprinklers are to be minimum 5.6
K-factor (80 K-factor) orifice approved
automatic sprinklers. Manual Control
Stations are to be the Model MC-1
described in Technical Data Sheet
TFP1382.
Provision must be made for installing
a 5.6 K-factor (80 K-factor) Inspector's
Test Connection at the most remote
location on the dry pilot line.
The Dry Pilot Actuation Trim is pro-
vided with a Model DP-1 Dry Pilot
Actuator, which is described in Tech-
nical Data Sheet TFP1380. The Actua-
tor is rated for use at a maximum pilot
service pressure of 50 psi (3,4 bar) and
a maximum water supply service pres-
sure of 250 psi (17,2 bar).
Graph B shows the minimum pilot line
service pressure as a function of the
water supply pressure. The pressure in
the dry pilot actuation system must be
automatically maintained using one of
the following maintenance devices, as
appropriate:
• Model AMD-1 Air Maintenance
Device (pressure reducing type), refer
to Technical Data Sheet TFP1221
• Model AMD-2 Air Maintenance
Device (compressor control type),
refer to Technical Data Sheet
TFP1231
• Model AMD-3 Nitrogen Maintenance
Device (high pressure reducing
type), refer to Technical Data Sheet
TFP1241
Supervision of the pressure in the dry
pilot actuation system and an alarm
that separately indicates operation of
the detection system is provided by
a low pressure alarm switch set as

field adjusted to a lower pressure, if
required.
The dry pilot line is to be provided with
low point drains to enable draining of
condensate.
Note: At a minimum, it is recommended that
internally galvanized pipe and cast iron fit-
tings be used for dry pilot lines.
Installation
The TYCO DV-5aAutomatic Water
Control Valve Dry Pilot Actuation is to
be installed in accordance with this
section.
NOTICE
DV-5A Automatic Water Control Valves
are designed to be used in freshwater
systems. When the supply is from an
alternative source such as brackish
water, saltwater, or contains additives
such as foam, the limited warranty is
reduced to one year from the time of
installation. An increase in frequency of
inspections is required when the valve
is exposed to such supplies and other
corrosive conditions or chemicals that
could impact valve materials or the
operation of the assembly. The system
and all components must be designed
accordingly for the increased demand.
It is required to thoroughly flush the
valve and trim assembly with freshwa-
ter and reset to the set condition after
each operation.
Proper operation of the DV-5aValves
depends upon their trim being installed
in accordance with the instructions
given in this technical data sheet.
Failure to follow the appropriate trim
diagram may prevent the DV-5aValve
from functioning properly, as well as
void approvals and the manufacturer’s
warranties.
The DV-5aAutomatic Water Control
Valve Dry Pilot must be installed in a
readily visible and accessible location.
Heat tracing of the DV-5aValve or its
associated trim is not permitted. Heat
tracing can result in the formation of
hardened mineral deposits that are
capable of preventing proper operation.
Always open the system control valves
slowly to avoid a sudden rush of water
entering the system.
The DV-5aValve is to be installed in
accordance with the following criteria:
Step 1. All nipples, fittings, and devices
must be clean and free of scale and
burrs before installation. Use pipe
thread sealant sparingly on male pipe
threads only.

NOTES:
The dew point of the pilot line air pressure must be maintained
below the lowest ambient temperature to which the dry pilot
actuation system will be exposed. Accumulation of water in the
pilot line connection to the Actuator will lower the air pressure
at which the actuator will open and possibly prevent proper
operation. Also, introduction of moisture into the pilot lines
exposed to freezing temperatures can create an ice buildup
that could prevent proper operation of the Actuator.
An air dryer must be installed where the moisture content
of the air supply is not properly controlled at less than the
required value.
It is recommended that an AMD-3 Nitrogen Maintenance
Device be utilized in dry pilot actuation system applications
where the dew point must be maintained below -20°F (-29°C).
Refer to Technical Data Sheet TFP1241.
Step 2. The DV-5aValve must be
trimmed in accordance with the Dry
Pilot Actuation trim illustration as
shown in Figure 5.
Note:If the addition of an Alarm Control
Valve is desired or required by the local AHJ,
the Alarm Control Valve noted as Item H in
Figure 8 is to be a separately ordered elec-
tronically supervised normally open valve.
Step 3. Care must be taken to ensure
that check valves, strainers, globe
valves, etc. are installed with the flow
arrows in the proper direction.
Step 4. Drain tubing to the Drip Funnel
must be installed with smooth bends
that will not restrict flow.
Step 5. The Main Drain and Drip Funnel
Drain may be interconnected provided
a check valve is located at least 12 in.
(300 mm) below the Drip Funnel.
Step 6. Suitable provision must be
made for disposal of drain water. Drain-
age water must be directed such that
it will not cause accidental damage to
property or danger to persons.
Step 7. Connect the Diaphragm Supply
Valve to the inlet side of the System
Main Control Valve in order to facilitate
setting of the DV-5aValve. See Figure
8.
Step 8. An Inspector’s Test Connec-
tion, as described in the Dry Pilot Actu-
ation section, must be provided for Dry
Pilot Actuation systems.
Step 9. An Air Maintenance Device,
as described in the Dry Pilot Actuation
section, must be provided for Dry Pilot
Actuation.
Step 10. A desiccant dryer, when
specified for Dry Pilot Actuation, is to
be installed between a drip leg and the
Air Maintenance Device.
Step 11. The Low Pressure Alarm
Switch for Dry Pilot Actuation is to be
adjusted as follows:
• Low pressure alarm setting at
approximately 6 psi (0,4 bar) below
the minimum pilot line service pres-
sure requirement shown in Graph B
• Fire alarm setting at approximately
15 psi (1,0 bar) below the minimum
pilot line service pressure require-
ment shown in Graph B
Step 12. Unused Pressure Alarm
Switch connections must be plugged.
Step 13. The Pressure Relief Valve pro-
vided with the Dry Pilot Actuation Trim
is factory set to relieve at a pressure
of approximately 45 psi (3,1 bar), which
can typically be used for a maximum
dry pilot actuation system pressure of
40 psi (2,8 bar). The Pressure Relief
Valve may be reset; however, it must
be reset to relieve at a pressure which
is in accordance with the requirements
of the authority having jurisdiction.
To reset the Pressure Relief Valve, first
loosen the jam nut and then adjust the
cap accordingly, clockwise for a higher
pressure setting or counter clockwise
for a lower pressure setting. After ver-
ifying the desired pressure setting,
tighten the jam nut.
Step 14. Conduit and electrical con-
nections are to be made in accordance
with the applicable standards of the
approval agency.
Step 15. Before a system hydrostatic
test is performed, the DV-5aDiaphragm
Chamber is to be depressurized, the
Automatic Drain Valve is to be tem-
porarily replaced with a plug, and the
Diaphragm Cover Bolts must be uni-
formly and securely tightened using
a cross-draw sequence.After tight-
ening, double-check to make certain
that all of the Diaphragm Cover Bolts
are securely tightened. See Table B in
the Care and Maintenance section for
torque specifications.

NOTICE
In order to prevent the possibility of a
subsequent operation of an overheated
solder type pilot sprinkler, any solder
type pilot sprinklers that were possibly
exposed to a temperature greater than
their maximum rated ambient must be
replaced.
Step 7. Operate (open) the Manual
Control Station (M) and then open
the Diaphragm Supply Valve (P). After
unaerated water ceases to discharge
from the Manual Control Station (M)
drain tube, slowly close the operating
lever by pushing it up. Do not close the
hinged cover at this time.
Step 8. After allowing water to flow out
of the Manual Reset Actuator (N) drain
tube until aerated water ceases to dis-
charge, reset the Manual Reset Actua-
tor (N) by pressing the Reset Knob and
hold until water stops flowing from its
drain tube and the pressure builds and
reaches approximately 15 psi (1,0 bar)
on the Diaphragm Gauge (K). Pressure
will then build up in the DV-5aDia-
phragm Chamber.
Note: After relieving trapped air, check the
Manual Reset Actuator (N) to make sure
there is no water draining from its drain tube.
If water is draining, reset the Manual Reset
Actuator (N) as previously instructed.
Step 9. Verify the ability for the DV-5a
Diaphragm to hold pressure as follows:
• With the diaphragm chamber pres-
surized per Step 8, temporarily close
the Diaphragm Supply Valve (P), and
then observe the Diaphragm Gauge
(K) for a drop in pressure.
• If a drop in pressure is noted, the
DV-5aDiaphragm is to be replaced
and/or any leaks must be corrected
before proceeding to the next step.
• If the Diaphragm Gauge (K) indicates
no drop in pressure, re-open the Dia-
phragm Supply Valve (P) and pro-
ceed to the next step.
Valve Setting
Procedure
Perform Steps 1 through 13 when ini-
tially setting the TYCO DV-5aValve,
after an operational test of the fire pro-
tection system, or after system opera-
tion due to a fire. See Figure 8.
Step 1. Close the System Main Control
Valve (B).
Step 2. Close the Diaphragm Supply
Valve (P). For Dry Pilot Actuation, close
the Dry Pilot Air Supply Valve (U).
Step 3. Open the Main Drain Valve (D),
System Drain Valve (E), and all auxil-
iary drains in the system. Close the
auxiliary drain valves and the System
Drain Valve (E) after water ceases to
discharge. Leave the Main Drain Valve
(D) open.
At this time make certain that the
Pressure Gauge Valves and the Alarm
Control Valve (H), as applicable, are
open.
Step 4. Depress the plunger of the
Automatic Drain Valve (F) to verify that
it is open.
Step 5. Clean the Diaphragm Supply
Strainer (Q) by removing the clean-
out plug and strainer basket. The Dia-
phragm Supply Strainer (Q) may be
flushed out by momentarily opening
the Diaphragm Supply Valve (P).
Step 6. Reset the automatic Dry Pilot
Actuation by replacing operated pilot
sprinklers and/or reset the remote
manual control stations. Re-establish
dry pilot pneumatic pressure.
Step 10. Partially open the System
Main Control Valve (B). Slowly close the
Main Drain Valve (D) as soon as water
discharges from the Main Drain Valve
(D). Observe the Automatic Drain Valve
(F) for leaks. If there are leaks, deter-
mine/correct the cause of the leakage
problem before proceeding.
NOTICE
When the System Main Control Valve
(B) is partially opened, the pressure on
the DV-5aDiaphragm Chamber may
increase. This increase in pressure is
normal, and if the pressure is greater
than the valve trim maximum pressure
rating provided in the Technical Data
section, the pressure is to be relieved
to at least the valve trim pressure rating
by partially and temporarily opening the
Manual Control Station (M); however,
do not allow the pressure as indicated
on the Diaphragm Gauge (K) to drop
below the supply pressure shown on
the Water Supply Gauge (J), since this
action may result in tripping of the
DV-5aValve.
Step 11. Close the hinged cover of the
Manual Control Station (M), and insert a
new break rod in the small hole through
the top of the enclosing box.
Step 12. Fully open the System Main
Control Valve (B).
Step 13. After setting a fire protec-
tion system, notify the proper authori-
ties and advise those responsible for
monitoring proprietary and/or central
station alarms.

Care and
Maintenance
The following procedures and inspec-
tions must be performed as indicated,
in addition to any specific require-
ments of the NFPA and any applicable
standards recognized by the Approval
agency. Any impairment must be imme-
diately corrected. See Figure 8.
NOTICE
If the water supply needs to be shut off
to the DV-5avalve and trim and cannot
be shut off upstream of the system,
close the System Main Control Valve
(B), the Diaphragm Supply Valve (P),
and the Inverted Flare Shut-Off Valve
(R). This will allow any trim above the
System Main Control Valve (B) to be
taken apart for service if necessary.
The frequency at which the following
procedures and inspections are to be
performed are to be in accordance with
the NFPA and any applicable specific
requirements of the standards recog-
nized by the Approval agency.
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system that
it controls, permission to shut down
the affected fire protection systems
must first be obtained from the proper
authorities and all personnel who may
be affected by this action must be
notified.
The owner is responsible for the
inspection, testing, and maintenance
of their fire protection system and
devices in compliance with this docu-
ment, as well as with the NFPA and any
applicable standards recognized by the
Approval agency. Contact the install-
ing contractor or product manufacturer
with any questions.
Some procedures in this section result
in the operation of the associated
alarms. Notify the owner and the fire
department, central station, or other
signal station to which the alarms are
connected before performing the tests.
It is recommended that automatic
sprinkler systems be inspected, tested,
and maintained by a qualified Inspec-
tion Service in accordance with the
NFPA and any applicable standards
recognized by the Approval agency.
Drop in Water Supply Pressure
Below Normal Range
NOTICE
If the water supply pressure is signif-
icantly reduced below the normally
expected static pressure range (as
could occur in the case of a water main
break or repair), and there is a subse-
quent drop in the diaphragm chamber
water pressure below its normal range
(for example, due to a leak in a piping
connection to or from the diaphragm
chamber or, a leak in the diaphragm
chamber check valve caused by dirt or
debris in the check valve seal area), a
deluge valve such as the DV-5acould
inadvertently trip, if its water supply
pressure is quickly restored.
A drop in the water supply pressure
to below its normal range (as in the
case of an interrupted water supply
condition) constitutes an emergency
impairment.
Should this condition occur, immedi-
ately close the System Main Control
Valve (B) and use the following proce-
dure to reset the system:
Step 1. Prior to the water supply pres-
sure being restored to the closed
System Main Control Valve (B), note the
pressure indicated by the Diaphragm
Gauge (K) and determine if the pres-
sure is within the normally expected
range.
Step 2. If the diaphragm chamber pres-
sure is below the normal range, check
for and correct any source of leakage
from the diaphragm chamber prior to
resetting the system.
Step 3. After the water supply pres-
sure is restored to the System Main
Control Valve (B), reset the DV-5aValve
in accordance with the Valve Setting
Procedure section.
NOTICE
For fire protection systems subject to
an emergency impairment caused by
an interrupted water supply condition,
it is recommended that consideration
be given to installing a low water supply
pressure switch with the appropriate
alarm/indications to monitor the water
supply pressure.
Waterflow Alarm Test Procedure
To test the waterflow alarm, open the
Alarm Test Valve (G), which will allow a
flow of water to the Waterflow Pressure
Switch (C) and/or Water Motor Alarm.
Upon satisfactory completion of the
test, close the Alarm Test Valve (G).
To ensure drainage of the alarm line,
depress the plunger on the Automatic
Drain Valve (F).
Dry Pilot Actuation
Operation Test Procedure
Proper operation of the DV-5aValve,
such as opening of the DV-5aValve as
during a fire condition, must be verified
as follows:
Step 1. If water must be prevented
from flowing beyond the riser, perform
the following steps:
• Close System Main Control Valve (B).
Open Main Drain Valve (D).
• Open System Main Control Valve (B)
one turn beyond position at which
water just begins to flow from Main
Drain Valve (D).
• Slowly close the Main Drain Valve (D).
Step 2. Open the Inspector’s Test
Connection.
Note: Be prepared to quickly perform
Steps 3, 4, and 5 if water must be pre-
vented from flowing beyond the riser.
Step 3. Verify that the DV-5aValve has
tripped, as indicated by the flow of
water into the system.
Step 4. Close the System Main Control
Valve (B).
Step 5. Close the Diaphragm Supply
Valve (P).
Step 6. Reset the DV-5aValve in accor-
dance with the Valve Setting Procedure.
Low Pressure Alarm and
Condensate Drain for Dry Pilot
Actuation Test Procedures
For Dry Pilot Actuation, testing of the
Dry Pilot Low Pressure Switch (T) and
drainage of the pilot line condensate
must be performed as follows:
Step 1. Close the System Main Control
Valve (B).
Step 2. Close the Diaphragm Supply
Valve (P).
Step 3. Open the Main Drain Valve (D).
Step 4. Open the Inspector’s Test Con-
nection, and slowly relieve pneumatic
pressure. Verify that the Dry Pilot Low
Pressure Switch (T) is operational and
that the low pressure set points are as
follows:
• Low pressure alarm setting at
approximately 6 psi (0,4 bar) below
the minimum pilot line service pres-
sure requirement shown in Graph B
• Fire alarm setting at approximately
14.5 psi (1,0 bar) below the minimum
pilot line service pressure require-
ment shown in Graph B.

Step 5. Close the Inspector’s Test Con-
nection and allow the Dry Pilot Line to
automatically repressurize.
Step 6. Individually open each low
point drain and then close after dis-
charge of any trapped condensate.
The gauge test valve to which the Dry
Pilot Line Gauge (V) is connected must
be used as a low point drain. Close the
gauge test valve, remove the plug, and
partially open the gauge test valve (as
necessary, collect water in a cup). After
condensate water ceases to drain,
close the gauge test valve, replace the
plug, and then completely open the
gauge test valve.
Step 7. Allow the Dry Pilot Line to auto-
matically repressurize.
Step 8. Open the Diaphragm Supply
Valve (P).
Step 9. Partially open the System Main
Control Valve (B). slowly close the Main
Drain Valve (D) as soon as water dis-
charges from the Main Drain Valve (D).
Observe the Automatic Drain Valve
(F) for leaks. If there are leaks, deter-
mine/correct the cause of the leakage
problem. If there are no leaks, the
DV-5aValve is ready to be placed in
service and the System Main Control
Valve (B) must then be fully opened.
Internal Valve Inspection
Once every five years during the
annual operational test procedure,
and prior to the DV-5aValve being
reset and the DV-5aValve de-pres-
surized, the interior of the DV-5aValve
must be cleaned and inspected for
wear and damage. Damaged or worn
parts must be replaced. Replacement
of the Diaphragm every ten years is
recommended, or more frequently if
inspections and/or wear and tear of
the Diaphragm warrants more frequent
replacement.
NOTICE
The Diaphragm Cover may be removed
between Steps 4 and 5 of the Valve
Setting Procedure instructions, since
at that point the DV-5aValve should
be de-pressurized as evident by a
zero gauge reading on the Diaphragm
Gauge (K) and Water Supply Gauge (J),
as well as no water discharging from
the Automatic Drain Valve (F).
To perform internal valve inspection
between Steps 4 and 5 of the Valve
Setting Procedure, remove the Dia-
phragm cover as follows:
Step 1. Close the Inverted Flare Shut-
Off Valve (R).
Step 2. Remove the Copper Tube
Fitting between the Diaphragm Supply
Valve (P) and the Inverted Flare Shut-
Off Valve (R).
Step 3. Loosen the union securing the
Dry Pilot Actuation Trim and remove the
Actuation Trim.
Step 4. Loosen and remove the union
between the Diaphragm Cover and the
MRA-1 Manual Reset Actuator (N) and
remove the MRA-1 Manual Reset Actu-
ator (N) subassembly.
Step 5. Remove the Diaphragm Valve
Cover hardware, then slowly remove
the Diaphragm Cover and perform
internal valve inspection. Clean the
valve interior and replace parts as
necessary.
After cleaning and inspecting valve
interior, and replacing parts as nec-
essary, reinstall the Diaphragm Cover
by completing the following steps to
assure the Diaphragm Cover Fasteners
are uniformly and securely tightened.
Step 1. With reference to Figure 1,
ensure that the Diaphragm is properly
oriented and that the proper hardware
arrangement is utilized when assem-
bling the Diaphragm Covers. The hard-
ware arrangements differ depending on
the size of the DV-5aValve.
Step 2. By first using the Long Hex
Bolts, support of the Diaphragm Cover
will be provided before installing the
Short Hex Bolts. Align Diaphragm in
proper orientation with Valve Body, and
then align Diaphragm Cover in proper
orientation with Valve Body. Hand-
tighten all fasteners.
Step 3. Using crossdraw sequence
to assure uniformity, wrench-tighten
Long Hex Bolts and Short Hex Bolts
to appropriate torque values. Repeat
crossdraw sequence two to three
times at incremental torque valves
until reaching the torque valves found
in Table C.
Step 4. Inspect to assure all Hex Bolts
are securely tightened.
Step 5. Using the union, secure the
MRA-1 Manual Reset Actuator to the
Diaphragm Cover.
Step 6. Using the union, secure the Dry
Pilot Actuation Trim.
Step 7. Replace the Copper Tube
Fitting between the Diaphragm Supply
Valve (P) and the Inverted Flare Shut-
Off Valve (R).
Step 8. Ensure that the unions and flare
fittings are securely tightened.
Step 9. With the Diaphragm Supply
Valve (P) closed, fully open the Inverted
Flare Shut-Off Valve (R) stainless steel
screw (approximately 1/2 in.) until
resistance is met so as not to break
the internal roll-pin. The internal roll-
pin stops the removal of the Inverted
Flare Shut-Off Valve (R) stainless steel
screw.
Step 10. Proceed with Step 5 of the
Valve Setting Procedures section in this
data sheet.
NOTICE
If the water supply contains chemicals
which tend to attack a polyester fabric-
reinforced, EPDM rubber or the five
year inspection indicates a build-up of
debris within the DV-5aValve that could
affect its proper operation, then the
frequency of the internal valve inspec-
tion procedure must be appropriately
increased.
With reference to Figure 1, make
certain that the Diaphragm is correctly
oriented; otherwise, the DV-5aDeluge
Valve cannot be properly set.
Under-tightening the Diaphragm Cover
Bolts can result in internal and external
leakage.
Use only TYCO replacement fasteners
as specified in Figure 1.
Do not apply adhesives, lubricants, or
other substances to the Diaphragm or
Valve Body.
